Re: dipstick
The part number is 628410A1 for the 170 dipstick in the C-145/O-300. Try El Reno Aviation in Oklahoma, they have many O-300 parts. Phone number is (405) 262-2387.

Re: dipstick
I think this issue may have been addressed some time ago, but I have an O300-B in my 172 TD and I am sure the dipstick is the one that was in the engine when the plane had the nose wheel. My question, is there a difference in the dipsticks for a 170 vs a 172 with the same engine?

Re: dipstick
Yes Frank. The oil level will be different on a stick for the same amount of oil when the aircraft is in a three point tail wheel configuration or more level when in a tricycle gear configuration. We currently have tricycle stick stick in N7A and I seem to recall there is a quart or more difference what it says we have and what we actually have. When we fill to 8 quarts at oil change the full level is about two inches higher (from memory) than the 8 qt full line on the stick.170C wrote:I think this issue may have been addressed some time ago, but I have an O300-B in my 172 TD and I am sure the dipstick is the one that was in the engine when the plane had the nose wheel.

Re: dipstick
Page 5 of the 1956 170 Owner's Manual states a seaplane will read a quart lower than actual level. So the reverse should be true that a 172 dip stick will read one quart higher than true level.170C wrote:I think this issue may have been addressed some time ago, but I have an O300-B in my 172 TD and I am sure the dipstick is the one that was in the engine when the plane had the nose wheel.

Re: dipstick
Of course what you guys are saying makes sense. I marked my dipstick so I know when it shows 7 quarts. I never fill to 8 quarts, even with a filter. I just wasn't clear if there was a different dipstick for the same engine depending upon in which aircraft it was installed.

Re: dipstick
This topic was discussed in depth previously, and Ol'Pokey was just as curious back then:

Re: dipstick
Would this picture be useful to anyone? I can email anyone a copy with double the resolution it has here.It seems to have good accuracy in my 170B on level ground as measured by adding oil to an empty sump.

Re: dipstick
Is it acceptable to 're-mark' a 172 oil dipstick for a 170 or should I be looking for the proper part?
I read a concern of weakening the stick by re-marking it but you'd have to really notch it deep for that, no?
I have a 172 stick (of course) and I'm trying to figure out the best/right solution.
My initial thought would be to drill (VERY) shallow holes at the proper levels for 8,7 and 6 quarts...under 6, add oil.
Thanks all.

Re: dipstick
The chief danger would be if someone unknowlegeable to your scheme operated or serviced the engine. The most-correct answer is probably to obtain the correct "oil gauge rod". A placard attached to your dipstick finger-loop might serve well in the interim.bagarre wrote:Is it acceptable to 're-mark' a 172 oil dipstick for a 170 or should I be looking for the proper part?

Re: dipstick
Good point on the unknowing not knowing my new markings.
That would require someone else changing the oil in my plane without me knowing so, I'm pretty safe there (for now).
However, I like the idea of having the proper oil gauge rod better.
Anyone have an extra one?
cheers.
